安装sonic插件实现flarum全局搜索

首先来到 sonic 官方 github：
https://github.com/valeriansaliou/sonic

注：下面编译sonic和docker运行sonic，二选一，sonic配置文件两者是一样的

编译sonic

编译sonic，由于sonic是rust写的，下面俺们来安装好rust，并配置好编译环境。

1、安装rust

curl https://sh.rustup.rs -sSf | sh

运行选择 1 默认安装，然后：

source $HOME/.cargo/env

检查：

cargo --version
rustc -V

2、配置编译环境和下载sonic源码：

安装依赖
apt install build-essential clang libclang-dev libc6-dev llvm-dev g++ -y

下载源码
git clone https://github.com/valeriansaliou/sonic.git

cd sonic

检查cargo
cargo check

开始编译
cargo build --release

编译好的二进制文件在下面文件夹
./target/release/sonic

复制文件到运行目录
mv sonic /usr/bin

3、编写配置文件

mkdir /etc/sonic

vi /etc/sonic/config.cfg

[server]

log_level = "error"

[channel]

inet = "0.0.0.0:1491"
tcp_timeout = 30

auth_password = "SecretPassword"

[channel.search]

query_limit_default = 10
query_limit_maximum = 100
query_alternates_try = 4

suggest_limit_default = 5
suggest_limit_maximum = 20

[store]

[store.kv]

path = "/var/lib/sonic/store/kv/"

retain_word_objects = 1000

[store.kv.pool]

inactive_after = 1800

[store.kv.database]

flush_after = 900

compress = true
parallelism = 2
max_files = 100
max_compactions = 1
max_flushes = 1
write_buffer = 16384
write_ahead_log = true

[store.fst]

path = "/var/lib/sonic/store/fst/"

[store.fst.pool]

inactive_after = 300

[store.fst.graph]

consolidate_after = 180

max_size = 2048
max_words = 250000

前台运行： sonic -c /etc/sonic/config.cfg

4、编写 systemd 文件后台运行

vi /etc/systemd/system/sonic.service

[Unit]
Description=Sonic Server
After=network.target

[Service]
Type=simple
ExecStart=/usr/bin/sonic -c /etc/sonic/config.cfg
Restart=on-abort

[Install]
WantedBy=multi-user.target

重载systemd
systemctl daemon-reload
启动sonic
systemctl start sonic
开机启动sonic
systemctl enable sonic

docker 运行sonic

docker运行搭配上面 3 的配置文件就可以了，docker和上面编译的sonic，二选一

docker run --restart=always -d -p 1491:1491 -v /etc/sonic/config.cfg:/etc/sonic.cfg -v /etc/sonic/store/:/var/lib/sonic/store/ valeriansaliou/sonic:v1.3.0

安装sonic插件

GitHub：https://github.com/ganuonglachanh/flarum-sonic

cd /var/www/flarum

composer require ganuonglachanh/sonic

去论坛后台开启sonic插件，保持默认配置就行

最后建立索引（安装后只运行这一次就行）

cd /var/www/flarum

php flarum sonic:addtoindex

php flarum cache:clear
